From Simulation to Suture Lines: Computational Fluid Dynamic Simulation-Guided Baffle Construction for Complex Biventricular Repair

Alexander K. Reed, Elena Sabdy Martinez, Alexander D. Kaiser +6

Biventricular repair is favored for children with complex double-outlet right ventricle (DORV) to eliminate the long-term morbidity of single ventricle physiology. However, creatin…

The Fluid Mechanics of Truncus Arteriosus

Karoline-Marie Bornemann, Perry S. Choi, Jay A. Huber +7

Truncus arteriosus (TA) is a rare, severe congenital heart disease in which the two main arteries exiting the heart fail to separate in utero resulting in one truncus and truncal v…
